Questions
- What is Ground Truth?
- Ground Truth preflights unfamiliar APIs, URLs, and claims before an agent trusts or acts on them. It returns observable evidence and a PASS, WARN, or FAIL decision signal.
- What is MCP?
- Model Context Protocol is the standard that lets AI apps call external tools. Ground Truth plugs into Claude Desktop, Cursor, and other MCP clients so your agent can verify before it acts.
- Do I need an API key or account?
- No signup form is required. The watch dashboard creates a private recovery key in your browser so your three monitors persist. Copy that key if you want to restore the workspace on another device or use the same monitors from an MCP client.
- How do the plans differ?
- All paid plans unlock the same tool set. The tiers differ only in active-monitor count (10 / 40 / 150) and monthly evidence-run quota (5,000 / 25,000 / 100,000). Pick the plan that matches the number of sources you need to watch.
- What happens if I cancel?
- Your workspace returns to the free monitor limits after billing becomes inactive. Your recovery key and monitor data remain associated with the same workspace.
